CARTRIDGE=SHELL EXTRACTGR.

SFEEFECATGN for-ning part of Letters Patent No. (Eld, dated Application filed January 1-1, E95. (No mod To all whom, it may concern:

Be it.' known that I. CHAnLns M. BURTON, a citizen of the United States, residing at New Haven, in the county ot' New Haven and State of Connecticut, have invented certain new and usel'nl improvements in Cartridge- Shell Extractors, ot" which the following is a specification, reference being` had therein to the accompanying drawings.

The metallic cartridges used in breech-loading hre-arms have an annular rib at one end known as the head ot' the shell. Among the most prominent functions of this head is the aiding in the removal of the cartridge shell from the gun'harrehwhich is accomplished by means of a latch or hook so arranged as to engage with this head and withdraw the shell from the chamber. lt quito frequently occurs `that this head ol' the shell is broken oi'i' from the body when a discharge takes place, whereby the usual means employed in extracting the shell is rendered inoperative as to removing the part ol" the shell remaining in the gun-barrel.

My invention relates to improvements in a tool or implement for extracting mutilated or headless shells from gun-barrels; and it consists ot' an implement composed ol' a hollow eXpansible cylinder provided with a reciproeating expanding-piston, and a movable latch or cam in the base ot the extractor, by which it is adapted to operate with the breech pin or bolt ot' the gun to extract the shell.

ln the accompanying drawings, Figures 1,2, and 3 are drawn on an enlarged scale,in which Fig. 1 represents a top view ot' my extractor, Fig. 2 a longitudinal central section on line on m in Fig. l. Fig. 3 is a front end elevation of the extractor. Figs. 4, 5, and 6 represent the position of the several parts in the act of engaging with and withdrawing the broken shell from the barrel when being used with a Winchester ritle.

` In the drawings, A represents a detached portion of abrecch pin or bolt, B a portion ot' a gun-barrel,C the body of a broken cartridge shell. The hollow cylindrical body u., having an enlargement or base, c, at one end, is provided with a series of longitudinal slots, o, which divide said cylinder a into a series of flexible divisions having the serrations m upon the end of each division, as shown, the outer diameter ot' the scrrations nt being such as will permit the insertion of the cylinder a inside of an empty shell, when the expanding-piston eis in the position indicated in Fig. 2. The piston e consists of a rod of two diameters concentric with each other, having a conical surface, e', near one end, and arranged to op crate in the tubular opening which passes through the center of the cylinder a and the base c. Said tubular opening converges to a smaller diameter at the serrated end of the cylinder a, whereby .the serrated ends n1. arc adapted to be expanded to a larger diameter and embedded into the inner surface ofthe shell C when the conical portion e of the piston e is driven forward as shown in Fig. 4.

ln the base c is au aperture, d, into which the ordinary extractor ot' the gun a enters when this device is being used, affording a safety clearance for the saine. Hinged to the base c by the pins h is a movable latch or cam, I), which is shown as having a bifurcation which adapts it for being connected with the peculiar form ci' the 1Winchester breech pin or bolt, as shown in Figs. 5 and 6.. As other styles ot' guns have a dil'terent forni of the breech pin or bolt. a modiiication of thelatch or cam b is necessary to adapt it for being used therewith.

Having described the several parts which constitute my invention, the operation and functions ot' the saine when being used are as follows, viz: The several parts having been placed in the positions shown in the sectional View, Fig. 2, and the breech pin or bolt A having been drawn baci; as tar as possible,the cylindrical body a is inserted from the rear of gun-barrel into the broken shell C remaining in the barrel, when the breecn pin or bolt A is moved forward, pressing the piston e i'orward too. The conical portion e of said piston, when thus forced into the convergent apertnre of the cylindrical body u, expands the body c to a larger dian'ieter, by which the serrationsmare embedded in the inner surface of the broken shell C, after which the movable latch or cam b is turned down upon the breechpin A, as shown in Fig. 5,which is a top view of the parts shown in Figs. t and 5. The enlarged end of the breech-pin will not pass through the bifurcation in the cam b. Consequently,\vhen the breeclrpin or bolt is drawn IOO backward by the proper mechanism provided for doing the same,the broken shell Gis thereby extracted from the chamber of the gunbarrel B, as shown in Fig. 6,

I am aware that eXtractors for removing broken shells from gunbarrels have been made and used prior 'to my invention. in which the serrated end ofthe extractor has been em pioyed, as set forth in Letters Patent No. 280,239, issued June 26, 1883; also the slotting of the body to render it flexible in connection with a taper pin for expanding the same, as set forth in Letters Patent No. 290,255, issued December 18, 1883. Therefore, I do not claim them, broadly; but

What I do claim as my invention, and desire -to secure by Letters Patent, is-

serrations m and base c, the expanding-piston e, arranged so as to expand the cylinder a when the breech pin or bolt A is pressed forward, and the hinged latch or cam b,arranged to operate in the base c and engage with the breech pin or bolt A, as and for the purpose set forth.

In testimony whereof I afIiX my signature in presence of two Witnesses.
